Resumen:
Nanomaterial properties depend not only on their size but also on their superficial state like ZnO nanostructures and ZnO nanowires (ZnO, NWs). Thus we devoted to controlling optical, electrical and chemical properties through the modification of their surfaces with organic and inorganic materials.ZnO is one of the most important and promising semiconductor, e. g. having a broad band gap, excitons possess ligation energies higher than those of thermal energy showing piezoelectricity and high isoelectric point. Understanding and controlling superficial processes affecting (1) gaps and electrons recombination, thus optical emission and absorption, (2) electrochemical processes are important for their application on luminescent emitting devices (LEDs, lasers), optoelectronic and electrical properties to apply in solar cell electrode and amperometric biosensors. Details given in the fabrication of ZnO nanostructures and NWs from vapour and colloids (electrophoretic and dip-coatingdeposition) and methods developed in relation to ZnO NWs transference from the growing substrate to more convenient surfaces. Discussing photo and electroluminescence in ZnO/MgO NWs structures and devices in ZnO NWs/PEDOT and ZnO with Ni films, absorption and optoelectronic properties in ZnO nanostructures sensitized by Ru and photoluminescence and electrochemical measurements in ZnO NWs/GOx (GOx=oxidase glucose).
